Tapered roller bearings HR30303J, Jiu Long (certified), bearing

Bearing large bearing mounting force required increased significantly, and should use hydraulic nuts and / or the use of grease: 1. When using a hydraulic nut mounting a bearing, it is necessary to position it in the journal threaded department or threaded sleeve, the annular piston abuts the inner ring of the bearing, shaft mounted on the axle nut or a ring true. By pump the oil into the hydraulic nut in a safe, precise installation force required to move the piston in the axial direction. Hydraulic nuts, spherical roller bearings mounted to 2. Using oiling method NACHI bearings monopoly, oil between the bearing and the journal injected under high pressure to form a layer of film. This layer of film separated from the mating surfaces of the bearing, significantly reducing the friction between the mating surfaces. When the bearing is mounted directly on the tapered journal, generally use this method, but also specifically for the oil injection method used in preparation of an adapter sleeve and put shirk install bearings. Oiler pump or generate the necessary pressure NSKKOYO bearings monopoly, the oil channel through the trenches and on the shaft or sleeve, the oil is injected between the mating surfaces. Design layout of SKF bearings needle roller bearings when to move, it is necessary to consider the layout of the shaft grooves and channels necessary. Spherical roller bearings mounted on a withdrawal sleeve with oil sump, oil is injected with the surface, and in turn tighten the screws, the withdrawal sleeve is pressed into the bearing bore. Bearing retainer to make orbital motion stability, should be used to guide the way the ring and give full attention to lubricate the guide surface of the tapered roller bearing structure NTN give improved high-speed conditions, the L-shaped guide roller cage change Z is ring ribs guided type cage. Bearing high-speed rotation, pocket a big gap NTN Bearing vibration amplitude is much larger than its cage pocket small hole gap cage vibration amplitude, so the value of the pocket gap is particularly important.
